SPECIFICATION forming part of Letters Patent No. 414,278, dated November5, 1889.

Application filed January 14, 1889. Serial No. 296,237. (No model.)

To all whom it may concern- Beit known that l, EDWIN D. BANGS, ofMilwaukee, in the county of Milwaukee, and in the State of lNisconsin,have invented certain new and useful Improvements in Oil-Oups forLubricating Locomotive and Other Engines; and I do hereby declare thatthe following is a full, clear, and exact description thereof.

My invention relates to oil-cups for lubri cat-ing locomotive and otherengines; and it consists in certain peculiarities of construction, aswill be fully set forth hereinafter, and pointed out in the claims.

In,V the drawings, Figure l is a vertical central section through thepreferred form of my device on the line l l of Fig. 2. Fig. 2is a planview of the same, with the cap removed and parts broken away.

A represents the cylinder of the cup, the upper part of which isexternally screwthreaded, as shown at c, for the reception of thecorrespondingly-screw-threaded depending circular ange b of the cap B,which latter has an upward-extendin g central neck C, having interiorscrew-threads for t-he reception of a correspondingly-screw-threadedplug D, having a central vertical perforation d for the admission ofairinto the cup above the oil, and below this neck the cap B is formedinto a central feed-hopper I, having a feed-opening t', to one side ofwhich is a vent c, preferably diagonal, communicating with the interiorof the cylinder A.

E represents a vert-ical column integral with the inside of thecylinder, provided with a vertical channel e, which also extends throughthe nipple E', which is externally screw-threaded for attachment to therods or pitmen or other moving part of the engine. The bottom A of thecylinder is tight, and from the same, on the inner side, directlyopposite the described column, there rises the curved guide F, for apurpose hereinafter described.

G is an arc-shaped sliding plate on top of the column E, (andadjustablysecured thereto by means of slot g in said plate and setscrew j passingthrough said slot into the top of said column,) while the other end ofsaid plate G is formed with an opening H, guarded I ad j ustm en t.

by inwardly-tapering walls h to form a funnel, the opening H being moreor less in register with the top of the vertical channel e, according tothe adjustment of the said plate G, whose edge adjacent to the inside ofthc cylinder A conforms in curve thereto.

My oil-cups may be provided, if desired, with windows K K, secured tothe cylindrA by suitable frames k k and rivets, as shown.

The Operation of my device is as follows: To determine the requisiteflow of the oil through the channel e, (which naturally varies accordingto the quality of the oil and the temperature of the air,) the cap B isremoved and the cylinder of the oil-cup is filled even full with oil,and the plate G adjusted to cover more or less of the channel e, andwhen the opening H in said plate is in such position with reference tothe channel e that the requisite number of drops per minute of the oilwill pass through said channele, then the set-screw j is tightened toplace, and the plate G thus secured in this preferred The oil is allowedto drain off till the space above said plate G is free, and then the capB is screwed to place, and the oil-cup is attached by its nipple E tothe part of the engine to be lubricated thereby. rPhe cap B isnotremoved to lill the cup, except in the first instance of testing theflow and adjusting the plate G, as just described; but the plug D isremoved and the cup replenished through the neck C, and when oil showsabove the opening z' of the feed-hopper I the cup is sufficientlyfilled, and then the plug D is screwed down to place, the space insidethe neck O below the bottom of the plug D and in the hopper I forming,with the space in the cylinder above the oil, an air-cushion, whichmaterially aids the flow of the oil through the channel e.

It will be understood that the part of the engine to which my oil-cup isattached has a reciprocating motion, and with each forward or upwardmotion of said part the oil inside the cup, directed by the curved guideF, is injected up over andkinto the opening between the walls h of theplate G, and thence finds its way through the opening H into the channele, and thence to the journal, slides, or other part to be lubricated,and this action will continue just so long as there is a single drop ofoil in the cup.

My device is not only extremely eicient, but is very economical as well,as it. will only feed while the enginel is in motion, and for thisreason and because by its use the actual amount of oil needed can bequickly and accurately ascertained the result is a great saving of oil,absolutely none being wasted With my device.

Another advantage lies in the fact that by reason of the straightchannel e the same cany be instantly and easily cleaned by thrusting aWire therethrough should it ever become clogged.

By reason of the described vent-c the cup can be readily filled, asdescribed, through the neck C and feed-hopper I, as the air in thecylinder will escape through said vent as fast as the oil from thehopper takes its place; and if any oil is forced through this vent c inthe motion of the cup when in use, it will fall intoi'the feed-hopper I,andthus directly feed back into the cylinder. The opening z' in thebottom of the feed-hopper I is below the Walls h of the entrance to thechannel e, andhence in the described operation of my device, when thesame has been filled to the point of said opening t', the oil in the cupcan only get into the channel e by the described motion of the cup, andwill be directed by the curved guide F directly to the funnel-entranceto said channel, as indicated by the dotted lines in Fig. l, thepressure of the "air above the oilbeing increased by the describedmotion of the oil-cup, and serving to drive the oil down through thechannel e, thereby making a sure and continuous feed, so long as the cupis in mot-ion.

In` case it is found more convenient to have the nipple E or part whichscrews onto the moving part of the engine in any other location thanthat shown, it will only be necessary to make a suitable connectionbetween the channel e in the column E and the chan- I have not deemed itnecessary to illustrate the same in the drawings.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In an oil-cup, the combination of vthe cylinder with a Verticalcolumn having a channel therethrough adjacent` to the Wall of saidcylinder and a curved guide for directing the courseof. the oil to saidchannel, substantially as set forth.

2. In an oil-cup, the combination of the cylinder witha vertical columnhaving a .channel therethrough adjacent to the Wall of said cylinder,the top of said column being below the top of said cylinder, and a caphaving a feed-hopper projecting down into said cylinder below theentrance to the said channel,

whereby the said channel can only receive oil when the oil is forcedabove said channel-entrance, as by the motion of said cup, substantiallyas set forth.V

3. In an oil-cup, the combination of the cylinder with a vertical columnhaving a channel therethrough adjacent to the wall of said cylinder, thetop of said column being below the top of said cylinder, and a caphaving a passage leading to said cylinder closed by a perforated plug,whereby there is always an air-'cushion above the oil in the cup,substantially as set forth.

4. -In an oil-cup, the combination of the cylinder with a verticalcolumn having a cha-n- `nel therethrough adjacent to' the wall of saidcylinder, an adjustable plate having an opening registering with saidchannel and surrounded by walls forming a funnel around said opening,said plate being adapted, by change of position, to more orless'closesaid channel, and a curved guide for directing the course ofthe oil into said funnel, substantially as set forth.

5. In an oil-cup, the combination of the cylinder with a vertical columnhaving a channel therethrough adjacent to the wall ofsaid cylinder, anda curved guide for directing' the course of the oil, with a cap having acentral feed-hopper and a central neck rising above said feed-hopper andcommunicating therewith, and a vent or lpassage between said' neck andthe cylinder below, and aperforated plug filling the upper part of saidneck, substantially as set forth. nel in said nipple; but this is soobvious that In testimony that I claim the foregoing I have hereunto setmy hand, at Milwaukee, in the county of Milwaukee and State of Wis`consin, in the'presence of two witnesses.
